The ECAT system is a web-based application designed to provide detailed parts lists for Kenworth and Peterbilt trucks and in-depth component catalogs for PACCAR Parts Fleet Services customers.

The system uses VMRS codes for industry consistent cataloging of components, such as diesel particulate filters and emission control-related components. Also, TRP Aftermarket Parts are easily identified using cross reference tools within the system, according to PACCAR.

“VMRS codes reduce confusion and potential entry errors since parts can sometimes have different names,” Karl Mowat, general marketing manager for PACCAR Parts, said in a written statement. “For example, an ABS tone ring might also be called a tooth wheel or an exciter ring.”

Fleet managers, shop technicians and parts personnel are now able to research parts and create electronic list orders without having to manually write down part numbers, Mowat says, adding that this “greatly reduces the chance of getting the wrong part.”

Once a truck’s chassis number is entered, the system retrieves a complete list of components and materials added to the truck by the manufacturer or body builder, Mowat explains. Alongside the list, a graphic of the truck is displayed. The user can click on an area of the truck and get a list of parts in that area. Or the user can find a particular part and the location of the part will be highlighted on the graphic representation. The user can also access service-wiring diagrams and get the failure type codes associated with certain parts.

The VMRS code system, which is a series of codes used to describe the maintenance operation of vehicles, was developed by the Technology and Maintenance Council of the American Trucking Associations in 1970 to reduce naming errors and updated 10 years ago. It refers to everything from parts to manufacturers to technician work to vehicle location. VMRS has 64 main code series. Code 33, which is at the heart of VMRS, is a series of nine-digit numbers that represent all of the parts and components on a truck. The first three numbers reference the truck system, such as brakes, or 013. The next three numbers reference the assembly, such as front, 001, or back, 002. The final three numbers are the component; such as a brake shoe, 014.
